LEWIS TANNING AND WILLIAM J. RYAN, OF NEW YORK, N. Y.

BOAT-HANDLING DEVICE.

To all whom it may concern:

Be it known that we, Lnwrs TANNING, a. resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, and WILLIAM J. RYAN, a resident of the city of New York, borou h of Manhattan, in the county and State 0 New York, and both citizens of the United States, have invented a new and Improved Boat- Handling Device, of which the following is a full, clear, and exact description.

Our invention relates to boat-handling devices, our more particular purpose being to enable a boat carried on shipboard, to be readily raised from the chocks, normally supporting it, and otherwise made ready for immediate action upon the water.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures, and in which Figure 1 is a side elevation showing a boat supported upon the checks, our improved mechanism being in position to enable either or both ends of the boat to be raised slightly from the chocks, the latter being at the same instant lowered; this view further showing the means whereby the gunwales are held securely while the boat is out of use; Fig. 2 is a front elevation of the mechanism shown in Fig. 1, this view particularly showing the position occupied by the checks while supportin the boat, and also showing one of the rol ers engaged by the keel and adapted to lift the boat by the partial rotation of a hand-operated lever; Fig. 3 is an enlarged fragmentary section upon the line 3 3 of Fig. 2, looking in the direction of the arrow, this view showing one of the rollers supporting the keel, and further showing a racket serving as a stop for limiting certain movements of the roller; Fig. at is a fragmentary section .upon the line 14: of Fig. 2, looking in the direction of the arrow, and showing one of the chocks, and also showing the rockin shaft, whereby both chocks are supported and Fig. 5 is a fragmentary section upon the line 5 5 of Fig. 2, looking in the direction of the arrow, and showing one of the spurs, whereby the gunwale chains are normally held down while the boat is out of action.

The boat is shown at 6, and is provided with gunwales 7 and with a keel 8. Rest ing upon a surface 9, which may represent Specification of Letters Patent.

the deck of a vessel, are cross beams 10. Mounted upon each of these cross beams are bearings 11, supporting a rocking shaft 12, having nearly the same length the beams 10. Two arms 13 are secured, one upon each shaft 12, these arms being upon the same side of the boat. At 14 are the chocks, which are mounted upon arms 15, 16, the latter being secured rigidly upon the shafts l2. Mounted upon each shaft 12, is a spur 17, these spurs engaging the lowermost links of chains 18. These chains are provided with turnbuckles 19, whereby they may be adj usted slightly as to length. The upper ends of these chains are provided with gunwale hooks 20, which engage the gunwales 7 of the boat.

Mounted upon the keel 8 of the boat, are brackets 21. Rollers 22, each having substantially the same thickness as these brackets, are mounted upon forks 23, the latter being secured rigidly upon the rocking shafts The operation of our device is as follows: The boat when removed from the water is rested upon the checks, as indi cated in Fig. 2, the arms 13 being brought into vertical position, as shown in Fig. 1.

The gunwale hooks 20 are next hooked upon the gunwales, and the lovers 13 moved slightly, so as to tighten the chains 18. The turiibuckles 19 are adjusted so as to remove any inequality in the length of the chains. The boat is now unable to move to any perceptible extent in any direction.

Suppose, now, it is desired to get the boat ready for the water. The arms 13 are turned by hand, as indicated by dotted lines in Fig. 1, and the shafts 12 turn slightly and move the spurs 17, thereby slackening the chains 18. The gunwale hooks 20 may now be removed from the boat if desired, or if not, they may be left secured in position, the loose chains being nicely thrown into the boat. The same movement of the shafts causes the forks 23 to turn, thereby slightly lifting the keel 8, and consequently raising the entire boat for an instant only, so as to disengage the spurs from the gunwale chains. A continuation of the same movement disengages the boat entirely and leaves it hanging in the fall, ready to swing out.

It will be noted that when the parts are in their normal positions, as indicated in Fig. 1, the weight of the boat tends to keep the forks 23 slightly inclined toward each other, so that the rollers 22 engage the brackets 21, serving as limiting stops for the same.

Having thus described our invention, we claim as new and desire to secure by Letters Patent:

1. The combination of a boat provided with a keel and with brackets mounted upon said keel, forks mounted independently of said boat and provided with rollers for engaging said keel and also for engaging said brackets, and means controllable at will for turning said for rs.

2. In a boat handling device, the combination of a rock shaft, choeks controllable thereby for supporting a boat, and mechanism connected with said rock shaft for raising the boat as the ehocks are lowered.

3. In a boat handling device, the eoinbination of a rock shaft, choeks mounted rigidly thereupon and adapted to turn radially therewith, a fork mounted rigidly upon said rock shaft and provided with a portion for engaging the keel of a boat, said fork and said checks all set at different angles relatively to said rock shaft, so that partial rotation of said rock shaft may lower said choeks and raise the upper end of said fork.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
